Most people dislike things that are complex. We crave simple things like sugar, salt, pleasure, and winning. Reality is nothing but complex systems interacting with other complex systems. Nothing in reality is simple if you examine it closely enough. When people simplify reality, they are only simplifying their view of reality. When something becomes too complex, it gets ignored or denied. Complex realities become unaccepted while they accept simple beliefs that do not exist. Their craving for simplicity overshadows their view of reality.
Reality that is complex does not make it unknowable. The only reality that people need to understand is the reality with which they interact. The average person need not know the reality of space or infinity. Understanding the reality that affects your health, relationships with others, and dealing with everyday problems only requires a basic grasp of reality. Depending upon the amount of reality acceptance in the society in which you live, understanding reality at a basic level is possible. Although reality is complex, individuals need not understand every aspect. Facts do not matter as much as understanding general concepts. Individual facts, names, and numbers are useful when talking to someone else about specific details of a subject, but they are unnecessary for a basic level of understanding.
Simple solutions only work on simple problems. The more factors involved in a problem, the more complex the solution must be. When people propose simple solutions for complex problems, they will ignore many factors. The simple solution may work for a short time or with a limited amount of people, but we must implement a solution that considers all factors if we will solve the problem for the most people. We must make compromises in dealing with complex problems. We cannot completely solve some problems. The goal in solving a complex problem is solving as high a percentage of the problem as possible. Complex solutions are not as satisfying as simple solutions, but they are necessary for handling complex problems.
Simpleminded strategies will work less well as sensible and well thought out strategies. If you quickly create a strategy, it will be a simple strategy. A well thought out plan will always consider more factors than a simple one. You may not always have the luxury of time for a well thought out plan. Emergency situations require quick and simple solutions. A simple strategy should be general enough to work in most situations. Most situations are not emergencies. Time restraints are usually self-imposed. Being late to work is not an emergency. If you are speeding in and out of traffic, you have chosen a simple strategy that will force you to make quick and simple decisions. If you get into an accident, it will be an emergency that was unnecessary and highly preventable. Taking the time for a well thought out strategy will help you make better decisions.
Craving simplicity is not a problem as long as you accept the complexity of the world. Understanding the complexity or offering solutions is unnecessary as long as you accept the entire reality of a situation. Complex problems involve many factors. Many of these factors will include other people. Each person must consider multiple factors to finding a solution that will satisfy the most people. As it involves more people, the more complex the solution will need to be. We can base even quick decisions on experience and a general knowledge of reality. Having knowledge of a complex reality is not as useful as understanding the general realities of the world. Simple solutions can not solve complex problems any more than complex solutions are necessary for simple problems. Accepting a general reality will help you much more than accepting simple solutions that do not address all the factors involved in complex problems.
